LEICA CLS 100X Cold Light Source Analysis Report

Device Identification

The device examined in the visuals is a professional cold light source unit used in laboratory and medical environments. Such devices are typically designed to provide high-intensity illumination via fiber optic cables for microscopes and macro imaging systems.

Brand and Model

As a result of a detailed visual inspection, a prominent red Leica logo was identified on the front of the device, and the inscription LEICA CLS 100X was found on the right side panel of the device. Based on this information, the product’s brand has been confirmed as LEICA and its model as CLS 100X.

Originality

Upon examining the print quality and typography of the logos on the device, as well as the overall craftsmanship of the casing, the product is assessed to be an original Leica production. Device-specific molded plastic components, not typically seen in aftermarket or replica products, are present.

Areas of Use

The LEICA CLS 100X is specifically designed for use with stereo microscopes. It serves as the main illumination unit in sensitive examinations requiring non-heating (cold) light, for illuminating biological samples, in industrial quality control processes, and for inspecting electronic circuit boards. The product does not provide illumination on its own; it is used by connecting a suitable fiber optic light guide (cable) to the black socket on its front.

Quantity Information

Only 1 main device is present in the visuals.

General Condition

The device is visually in “used” condition. Its casing retains its integrity but is not in new or mint condition. The overall appearance of the device indicates that it was previously used in an active working environment (likely a laboratory or hospital).

Physical Deformation

No breaks, cracks, or major dents have been detected on the device’s outer casing. However, beige plastic surfaces show color changes (slight yellowing) and surface stains due to use and age. Dust accumulation and light scuff marks are visible on the black top section and the handle. Dirt accumulated around the controls on the front panel indicates that the device has not undergone detailed cleaning for some time.

Mechanical Components

The mechanical controls on the front of the device are in place:

• Illumination Intensity Adjustment: On the left side, there is a mechanical rotary knob rated from 1 to 6. The knob appears physically sound.
• Power Switch: In the lower left corner, there is a green “I/0” marked rocker-type on/off switch. The switch is in place and no physical damage is observed.
• Carrying Handle: The dark-colored section on the top of the device also functions as a carrying handle and is in sound condition.

Accessories

The electric power cable or the fiber optic cable (light guide) required for the device to operate are not visible in the visuals. The product is shown only as the main unit (casing). The black cylindrical part on the front panel is not an accessory but the socket input where the light cable is connected.

Battery Status

This device is a unit powered by mains electricity (AC). It is not a portable battery-powered model; therefore, no internal battery inspection has been performed.

Label Information

On the front lower part of the device, there is a yellow inventory label, likely belonging to the institution where the device was previously used. The information read on the label is as follows:

• Institution Name: midt regionmidtjylland (It is understood to be a healthcare institution in the Central Jutland Region of Denmark).
• Department: Medico-teknisk afdeling (Medical-technical department).
• Inventory/Tracking No: 134043

Dimensions and Compatibility

The device is sized as compact desktop laboratory equipment. The light output socket on the front panel appears compatible with standard fiber optic light guides (typically for standard diameter tips compatible with Leitz/Leica).

Current Faults

No physical evidence (burn marks, broken sockets, detached parts, etc.) indicating that the device is “faulty” has been found during the visual inspection.

Potential Fault Risk

Depending on the age and used condition of the device, the internal halogen lamp may have reached the end of its life (the lamp is a consumable). Furthermore, as the rear or bottom part is not visible, no comment can be made regarding the condition of the power input socket and fuse holder. However, based on its external appearance, since it has not suffered a severe impact, there is a high probability that its electronic circuits and mechanical switches are in working order. The most likely maintenance needs could be lamp replacement or internal fan cleaning.
